During minimally invasive surgeries, such as laparoscopic surgery,trocars are used to permit access into a patient's body. Trocars aremedical devices or instruments that comprise hollow tubes or hollowportions. During surgery, such as laparoscopic surgery, a trocar may beinserted through an incision into a patient's body, such as into theabdominal or pelvic cavity of a patient. The trocar acts as a passagewayfor other surgical tools or devices, such as scopes, laparoscopes,microscopes, knives, graspers, scissors, staplers, and more, to enterthe body for use during surgery.

During such surgical procedures, the lenses of viewing devices insertedinto the body through the trocar, such as scopes, laparoscopes and/ormicroscopes, may become clouded, or the view therethrough may becomepartially or completely obscured. The view can be obscured, eitherpartially or completely, if the lenses are smeared with bodily fluids orthe like, or if the lenses become clouded or fogged over due to thehumidity within the body of the patient. In addition, the interior ofthe trocars should also be kept clean.

An object of the present application may be to provide a cleaning devicefor a trocar and surgical scopes, which cleaning device may be utilizedduring surgery. The cleaning device also may be used to defog lenses oroptics of a surgical scope.

DESCRIPTION OF THE INVENTION

FIG. 1 shows a trocar 10 used in minimally invasive surgery. The trocar10 has a cleaning device 12 removably connected thereto. The cleaningdevice 12 as shown is snapped onto to the trocar 10 using a snap member14. However, this is not to be construed as limiting the presentdisclosure as any suitable attachment element, such as a hook-and-loopfabric, buckles, clips, tape, etc., configured to securely and removablyattach the cleaning device 12 to the trocar 10 may be utilized.

An embodiment of cleaning device 12 is depicted in FIG. 1 in an explodedview. The cleaning device 12 comprises a casing 15 having the snapmember 14 attached to an outside rear surface thereof. A firstdepression 24 may be formed in an upper surface of the casing 15 ofcleaning device 12 to receive a sponge 20. In one example, the sponge 20may be impregnated with a cleaning medium 22. The casing 15 may furtherinclude a second depression 26 formed in an upper surface thereof anddisposed opposite the first depression 24. The second depression 26 maybe configured to receive a heating element therein. In one example, theheating element can comprise batteries 16 and a heating coil 18operatively connected to the batteries 16. The heating coil 18 may beconfigured to warm a microscope, laparoscope, or other surgical scope(not shown) so that the scope is ready for reinsertion in the trocar 10and ready for reinsertion into the body of the patient being operatedupon. Instead of batteries 16 and heating coil 18, a chemical packhousing chemicals that combine in an exothermic reaction, such as isused by skiers in their gloves to keep their hands warm while skiing,may be used as the heating element.

In one exemplary use of the cleaning device, the scope being utilized ina surgical procedure is removed from the trocar 10. It is first wipedoff on the sponge 20, thereby to remove matter from the patient whichhas built up during the surgical procedure or which has condensed uponthe scope during the surgical procedure. The heating element is thenused to heat the front of the scope, thereby heating the front of thescope above the temperature of the patient to discourage the formationof condensate on the front of the scope when the scope is within thebody of the patient. One or more lights 36, such as light emitting diode(LED), may be positioned on casing 15 and used to provide illuminationfor the trocar 10 and the site where the trocar 10 is inserted into apatient. The lights may be operatively connected to batteries 16.

FIG. 2 shows a top view of the cleaning device 12 attached to a trocar10. The second depression 26 may further include a heating chamber cover28 positioned over the top thereof to provide protection for the heatingelement. The heating chamber cover may further include a microfiberholder 30 formed therein configured to hold a microfiber cover 31. Theheating chamber cover 28 and the microfiber cover 31 may be configuredwith at least one scope access hole 32 which permit the microscope orother scope to be inserted into heating chamber 33 to be warmed byheating coil 18, heating pack, or some other manner known in the art.Microfiber cover 31 may be used by surgical staff to wipe debris and/orfluids from a scope in order to clean the optics thereof prior toinserting the scope into the scope access hole 32 to be heated. In anembodiment, microfiber cover 31 may be disposed on heating chamber cover28 within the holder 30 in order to provide easy access to surgicalstaff.

With further reference to FIG. 2, in one example, casing 15 may have asubstantially isosceles triangular shape when viewed from above, withthe two sides of the triangle that are not of equal length not adjacentto the trocar 10. Such a configuration may have the benefit ofoptimizing placement of the heating coil 18 and batteries 18 in casing15 next to sponge 20. This configuration also may have the benefit ofproviding easy access to cleaning device 12 while minimizinginterference of the device with access to the surgical site while thecleaning device 12 is attached to the trocar 10 during a surgicalprocedure.

In FIG. 3, the trocar 10 is shown again with the cleaning device 12attached thereto by snap member 14. An advantage of such an embodimentis that it places cleaning device 12 in close proximity to trocar 10,and thereby provides easy access to surgical staff. Such an embodimentalso has the advantage that cleaning device 12 does not need to be seton a separate tray.

With reference to FIGS. 3 and 4, sponge 20 is shown in its installedposition in first depression 24 in casing 15. Sponge 20 may be comprisedof any material known in the art. Sponge 20 may be used for cleaningdebris and/or fluid from a scope. Sponge 20 also may be impregnated witha cleaning medium 22, such as a cleaning and/or defogging fluid. In anembodiment, cleaning medium 22 and or sponge 20 may be sterile.

FIG. 4 shows the trocar 10 with an embodiment of cleaning device 12 froma different angle than the previous figures. Holes in microfiber cover31 and heating chamber cover 28 create the scope access hole 32, whichallows a scope to access heating chamber 33 in second depression 26,where heating coil 16 may warm and aid in defogging a scope. Debris maybe wiped from a scope's optical components by surgical staff onmicrofiber cover 31 and/or sponge 20, which may be impregnated withcleaning medium 22.

FIG. 5 is another exploded view of the cleaning device 12 having thecasing 15. The casing 15 comprises an attaching mechanism, such as snapmember 14, which is configured to attach to a trocar. Snap member 14 isconfigured to removably attach to trocar 10. Other embodiments of casing15 may be configured to attach to trocar 10 with tape, a friction fit,or through another mechanism otherwise known in the art.

The casing 15 also comprises a first depression 24, which is configuredto hold a sponge 20. The sponge 20 may be at least partially moistenedwith a cleaning solution. The casing 15 also comprises second depression26 which is configured to hold batteries 16 and heating coil 18 or adefogger, and forms heating chamber 33. Second depression 26 may holdone or more batteries 16, which in an embodiment includes three lithiumbatteries. In other embodiments, other types of batteries 16 may be usedor adapted for use, and other numbers of batteries may be used. Inanother embodiment, another heating source, other than an electrical orbattery-powered heating source, could be utilized, such as a chemicalheat source or chemical heat pack, which would avoid the use andultimate disposal of batteries, which can present challenges due to thepotential environmental impact of battery waste.

The second depression 26 and heating chamber 33 of the casing 15 may beat least partially covered by a heat chamber cover 28. The heat chambercover 28 may comprise the microfiber holder 30 and a scope access hole32. A scope or microscope may be inserted into the scope access hole 32and through the heating coil 18 or defogger. The scope or microscope maybe wiped on the microfiber cover 31 disposed in the holder 30 before orafter insertion into the scope access hole 32.
